TECHSPEC® Fused Silica Wedge Prisms

By: Edmund Optics

Edmund Optics® (EO), the premier provider of optical components, introduces new coating options for TECHSPEC® Fused Silica Wedge Prisms. These versatile prisms are designed for a wide variety of beam steering applications using an Nd:YAG laser. TECHSPEC® Fused Silica Wedge Prisms are specifically designed to provide high transmittance at the first through fourth Nd:YAG harmonics. New laser line coatings provide Rabs <0.25% at the design wavelength and offer guaranteed laser induced damage thresholds of 3 J/cm2 at 266nm, 7.5 J/cm2 at 355nm, 10 J/cm2 at 532nm, and 15 J/cm2 and at 1064nm, with a 20ns pulse duration and 20Hz pulse repetition rate. Superior system performance with ?/10 surface flatness Precision TECHSPEC® Fused Silica Wedge Prisms are optimized to ensure the highest level of system performance using tightly controlled specifications including ?/10 surface flatness, 20-10 surface quality, and a 15 arcsecond wedge tolerance. To alter a beam path, TECHSPEC® Fused Silica Wedge Prisms use one prism surface that is orthogonal to the optical axis and one wedged surface. When two Nd:YAG prisms with the same wedge deviation are used, this creates a risley prism pair, which allows for custom beam steering of up to two times the deviation. With diameter tolerances of +0.0/-0.1mm, these laser line coated prisms are available in diameters of 12.5mm and 25.0mm with nominal deviations from 0.5° to 5.0°. TECHSPEC® Fused Silica Wedge Prisms are in-stock and available for immediate delivery.
